## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arbitrum-defi-overview-289853c5 -d '<json body>'
```

Example prompt: Give me a full DeFi overview of Arbitrum — I want to see the TVL trend, which protocols are on top, stablecoin breakdown, DEX volume, and fee data right now.

## When to prefer this

Use this endpoint when you need a broad, multi-metric DeFi overview of Arbitrum specifically — covering TVL, protocols, stablecoins, DEX volume, and fees in a single call. Prefer it over protocol-specific endpoints when the user wants ecosystem-level insight rather than details on one protocol. For other chains (Solana, PulseChain, Rootstock), use the corresponding chain-specific sibling endpoints.

## Known failure modes

- Upstream DefiLlama data unavailable — may return stale or empty data
- Payment failure (x402) if USDC balance insufficient or payment header missing
- Timeout if aggregation of chain data takes too long
- Empty or partial response if Arbitrum data is temporarily missing from the source
